!> \brief collects all references to literature in CP2K
!>      as new algorithms / method are included from literature sources
!>      we add a citation, to give credit to the authors
!>      (often ourselves, but this need not to be the case), and as a form
!>      of documentation.
!>
!>      reference_manager.F provides an easy way to cite these references from the code
!>      (e.g., whenever the relevant part of the code is executed)
!>      and to add citations to the input
!>      at the end of the run a bibliography is printed that can be used, e.g., in papers
!> \note
!>      references need to be input using the ISI citation format, because it is
!>      uniform, easy to parse, and can be exported for example from web of science.
!>      (mark the reference, and click 'export to reference software', open the resulting file)
!>      Furthermore, it can be easily converted to and from using the bibutils tools
!>      a collection of easy to use conversion programs that can be found at
